実験手順

The product from step (1) (7.2 g, 14.3 mmole) trifluoroacetic acid (40 ml) and thioanisole (8.38 ml, 71.5 mmole) was refluxed in a nitrogen atmosphere for 3 hours. After cooling the trifluoroacetic acid was removed by rotary evaporation and the oily residue was stirred with ice and water and basified with aqueous ammonia (S.G. 0.880). The resulting suspension was filtered and the solid was washed successively with water, ethyl acetate and diethyl ether and then dried to give 4-(4-(2-methoxyphenoxy)-anilino)-3-cyano-6-methoxy-7-hydroxyquinoline.
